Mary and I had been married twenty years and like a lot of marriages of long duration ours had become somewhat complacent, at least as far as sex went. It had nothing to do with physical attraction; Mary was still a pleasure to look at, it was just that after twenty years sex had become boring - there was no excitement any more. Mary was great in bed when the mood hit her; it just didn't hit often enough. Even though she had a great body, with world class tits, she always hid herself in very conservative clothes and wore 'sensible' shoes. She did have a few pair of high heels that she called her "I'm in the mood to fuck" shoes, but she never wore them outside the bedroom. She had no interest or desire in ever trying anything new or exciting. She'd only had one man before we were married and as far as I knew I was the only other man she'd ever been with.

Once on a trip to Detroit on business I bought a couple of magazines to read at night in my hotel room. One was Penthouse Letters and for some reason that I was never able to fathom I got really turned on by reading the letters from men who liked watching there wives with other men. I tried to imagine Mary with another man, but I couldn't. However the more I read the more I thought about what a kick it would be to see her with someone. I knew my sweet conservative Mary would never do something like that, but I had a good imagination and that was enough.

Our sex life got a little less boring as I read every issue of PHL that I could find, imagined the letters were about Mary and then rushed home to fuck her while the image of another man between her legs was still with me. Mary is not stupid and she began to ask me what had gotten in to me lately. I just smiled and said I was rediscovering what a sexy woman she was. As an added bonus it seemed like the more I fucked Mary, the more she wanted to fuck.

I had a business trip to New York that was scheduled for the week of our twentieth anniversary and I asked her if she would like to go with me and she said yes. We checked into the hotel and when Mary unpacked her suitcase she found that I had slipped all three pair of her high heels in her bag. She gave me a strange look when I asked her to wear a pair to dinner. She looked at her shoes and then back at me and then went back to digging in her bag looking for a dress she could wear with them. Just before we left the hotel room I asked her to do me a favor and go without a bra. Again she gave me a strange look and then she took it off.

On the cab ride to the restaurant I slid my hand up her leg and she kept glancing nervously at the back of the cabbie's head, but she didn't stop me. As we walked into the restaurant I imagined that every male eye in the place was on her, and in fact many were. She didn't realize it, but the thin material of her dress brushing up against her nipples had hardened them and when the lighting was just right you could see them. I looked around the room and saw several men quickly glance away and I wondered how many of them would have fucked Mary if they could have. We were seated in a booth and after we had given our order we made small talk as I ran my hand up her leg and stroked her mound.

"Do me another favor?"

"What?"

"Go to the ladies room and take off your panties."

She gave me a long look and then got up and walked toward the rest rooms and I watched her full breasts sway under the thin fabric of her dress and I looked around and saw other male eyes looking at the same thing. When Mary came back and sat down I again ran my hand up her leg and this time I probed her opening with my fingers.

"What are you doing?" she asked.

"Getting you hot enough to fuck" I replied.

She giggled, "Here? On the table?"

I chuckled and said "I'm game if you are, but as sexy as you look tonight half the guys in the room would line up behind me. Think you could handle them all?"

And my lovely, shy, conservative wife surprised the hell out of me, "I'd do it for you lover, but you have to promise to hold my hand while I do it."

I stared at her and she giggled, "What's the matter lover? Don't think I'm woman enough?"

This was a totally different Mary sitting across from me and I wondered if it was because we were in a strange city, or maybe something in the water.

"Before we take such a big step," I said, "Let's try a couple of smaller ones. Unbutton the top two buttons on your dress and lets give the waiter a good look at your tits."

She looked me right in the eye and slowly unbuttoned the top three buttons. If she moved to quick either one or both of them would fall out. We got the best service I've ever gotten in a restaurant; the waiter was constantly coming by to ask if everything was all right and one of the bus boys came by every few minutes to refill our water glasses. Mary would lean forward to pick up the glass and when she did both the bus boy and I were sure that her luscious 36C cup melons were going to fall out of her dress. The waiter was broken hearted when we left and we didn't see the bus boy. The poor kid was probably in the men's room whacking off.

As we walked out the front door of the restaurant Mary said, "Okay, that was one small step. What's the next one?"

No sir! Not my Mary at all.

"How far are you willing to go?" I asked.

"How far are you willing to take me?"

A dare if ever I heard one.

"Lets walk for a spell" I said and we headed in the direction of our motel. We had gone about two blocks when we saw a man walking toward us. I told Mary to drop her purse just before the man got to us, bend over to pick it up and let her tits fall all the way out of her dress. Now there was no way in hell that my Mary was going to do something like that, but this Mary did. The man was three feet from us and she dropped her purse, bent to pick it up and her beautiful tits fell out of the front of her dress. She gave him a good look at them and then covered up, "Oh I'm so embarrassed" and as he passed by shaking his head Mary stood up and said, "Another small step out of the way. What's next?"

I flagged down a taxi and as soon as we were settled into the back seat I ask Mary if she felt like sucking my cock. She didn't hesitate a milli-second. Her hands went to my fly and in seconds she had my dick in her mouth. I saw the cab driver watching in his rear view mirror and after about two minutes she said, "Is he watching?" I said yes. "Think he might want one too?"

I was caught flat-footed by that one and it took me a few moments to recover. "Ask him" I said.

"Oh no. I said I was willing to go as far as you are willing to take me. You ask him."

As I sat there not knowing what to do or say Mary brought me off and did something that she had never done in twenty years of marriage - she swallowed my cum. No, that's not right; she greedily gulped and sucked every drop out of me and when she was done she tucked me back in and gave it a little pat.

All right, I thought, here goes nothing, "Your turn Mac" I said to the back of the cab drivers head. He immediately went across three lanes of traffic with every horn in New York blaring at him and pulled into an alley. He climbed in the back seat with Mary and she didn't even look in my direction before going down on him. I spent most of my time watching Mary's head bob up and down in the cabbie's lap, but I did notice that the ungrateful bastard had left the meter running. It took Mary almost five minutes to get the driver off and when she did she swallowed everything he had too. When he dropped us off at the hotel he said, "No need to tip me man. She already done that" and he handed her his card.

"Call me when you need a cab and I'll see that you get the best service in the city."

As he pulled away from the curb Mary said, "What's next?"
